Combat: Serpent lords regard themselves as healers and scholars, not fighters.
Serpent lords are powerful monarchs. As king or queen of the snakes in a 20-mile radius of their lair, they can summon 10-20 normal and giant constrictors, 10-60 normal and giant poisonous snakes, and 10-40 spitting snakes to their defense if given enough time (1-4 days). The reptiles normally found in the serpent lord’s company are regarded as his friends and family as well as his guardians. They will not be sacrificed in combat foolishly or haphazardly. The serpent lord will personally protect his lesser cousins against powerful adversaries and predators.
Perhaps the biggest concern for the serpent lord and his protecting snakes is the acquisition of food.
Serpent lords are sages as well as powerful healers. They are specialized in the the lore of herbalism, magical potions, and clerical magic in general. They are sometimes the guardians of a powerful clerical or religious magical item (like a Book of Exalted Deeds or a Sword + 5, Holy Avenger), yielding it up to whoever can perform a preordained quest.
